@medwinter@mastodon.social fair enough! if it's any consolation, the Switch version removes Mingle PP entirely so instead, pins only evolve from shutdown PP and Battle PP. Tin Pin PP counts as battle PP, and if a Pin already has an evolution route for shutdown PP, the Mingle PP route uses Battle PP. if it doesn't, it uses Shutdown PP instead.
If it already has both tho, you gotta... I dunno, balance both shutdown AND battle PP apparently. but that's rare mercifully ._.;
